Georgette said: "Later Giles phoned him then he apologised unreservedly." She added: "Ironically Mitch losing his temper at Giles has helped Amy and Blake.

"It has brought home the seriousness of their problems and they are now tackling them."

Amy, who was left in tears by the spectacle, then confessed to both families that she and Blake were badly addicted to drugs.

Georgette said: "There was lots of emotion."

Georgette rang the Harley Street GP who rushed to the hotel and arranged for them to have urgent treatment in the US. She went on: "Both families are just very pleased and proud for them to recognise they have a problem and that they are making steps to cure it.

"They couldn't have done it separately - it's something they had to do together. It's very reassuring to know they are getting the help they need.

"They're both lost but we are going to get them back. They have to take control of their lives."
